Orchestrator - How to create 1 batch for multiple vouchers P0411

Hi there,

I'm looking for more information on how to create an orchestration that uses one batch number for multiple AP vouchers (P0411). I'm on tools 9.2.4.1 and see bug 29749349 gives some vague details:

This use case can be accomplished with the Object input type added for 
9.2.3.4, Studio 7.3
This use case requires passing an array of vouchers, with each voucher being 
an array to load the voucher grid.
So the first step is to create the batch and first voucher.
Then iterate over the array of vouchers using the batch just created to add 
all the rest of the vouchers.

Has anyone accomplished this? I have created an orchestration that processes multiple AP vouchers from a csv file but each voucher is processed in a separate batch.
